A machine for feeding and simultaneously binding pairs of relatively small spiral wire bound pads. Groups of sheets of twice the final desired size are fed serially to a station where they are split and separated. Pairs of the split pads are then fed through a conventional coil binding machine having stations where they are successively aligned and receive a single spiral binder while in side-by-side and slightly spaced relationship. At the next station cutter means are provided for simultaneously trimming and inwardly bending both the outer and the inner ends of the binders of both pads. The two trim-cutting and bending assemblies for the outer ends are of conventional construction having a fixed cutter member and a movable blade operated by a cam with a diagonal slot. The trim-cutting and bending assembly for the inner ends however is of novel construction, comprising two fixed cutter members carried by a single arm and spring-urged movable cutter blades actuated by a V-shaped cam on another arm.
